Abstract: 697,312. Packaging lump sugar. BARDET, G. June 27, 1949, No. 16954/49. Class 94(i) [Also, in Groups VI and XXX] A turret 3, rotated about a fixed vertical shaft 2, Figs. 1, 2, carries around its periphery, eight camoperated shearing and packaging devices of identical construction and operation each of which cuts a set of bars of sugar transversely and packs the so-cut sugar as one of three layers into a container carried in the device. An empty container on a table 14 adjacent the periphery of the turret is pushed on to a support 17 of one of the devices, by an L-shaped member 5 of the device which is moved radially by lever means 6, 8, 9 actuated by a roller 10 running in a cam groove 11 of a non- rotatable member coaxial with the turret. This cam member is lifted by means driven from a shaft rotating 8/3 times as fast as the turret to render the arm 5 operative to take in a container once for each device in every three revolutions of the turret. The container support 17 is lifted by a follower 19 co-operating with a cam face brought into an operative position after the container has been fed into the device, by link means actuated by the shaft rotating 8/3 times the speed of the turret. A group of sugar bars on a belt conveyer 23 is removed laterally into a frame 29 of a device, where the group is held by a spring-pressed side bar, by a rake 24 slidable in the device and moved radially inward by link means having a roller engaging a cam groove 90 in the base of a fixed disc 27. A depresser 36 is then moved down, by link means having a roller engaging in a peripheral groove 37 in the disc 27, to force the group of bars into a shearing frame 26 in which they are retained by a spring-loaded finger. The frame 26 is then moved towards the axis of the turret to an innermost position, where the bars are cut by opposed knives 28, 28<SP>1</SP> actuated by lever means 40 in engagement with a fixed cam ring 43, and then moved step by step outwardly, being cut at each step, until the original position is reached. The frame 26 is carried by a slide 32 guided on a radial rod 34 carried by the turret and moved along the rod by the engagement of a roller 33 on the slide in a cam groove 35 of the fixed disc 27. The depresser 36 is moved down again to force the cut bars into the container to form a layer therein, spring catch means 21 allowing the container on the support 17 to be forced downwards as each of the three layers is pressed into the container which is held open by funnel shaped springs 22. After being filled, the container is pushed from the device by the member 5. A cam 45 ensures that the container is lowered to the discharge position if a layer of bars is not presented to it. In a modification, Figs. 10, 12,-a group of bars is fed directly from a conveyer 51 by a turnstile 53 into a cutting frame 54, of a device on the turret, two pivoted sides of the frame 54 being open to receive the bars but being closed by cam means to hold the bars when the frame is moved inwardly to the bar cut-' ting position; an annular metal plate 91 supports the bars in their outer position but is apertured for passage of bars therethrough to a container below. The depresser 36 is operated by rack and pinion means actuated by the engagement of a roller 72 in a cam groove on the top of the fixed disc 27. Empty containers received in three-sided frames 74 on a chain conveyer 75 which runs around the turret are lifted from these frames 74, at a position E, by a bracket 17, of one of the devices, actuated by rack and pinion means having a roller 19 engaged in cam groove 145 periodically lifted into operative position, the bracket 17 being moved downwardly, as a layer of sugar is pressed into a container in the bracket, against spring and pawl means. A guide funnel 98 between the bracket 17 and the frame 54 is actuated by lever mechanism having a roller engaged in a cam groove 90 of the disc 27 to rise to the level of the frame when the cut bars are to be pressed therefrom. A filled container is removed by the chain conveyer 75.
